Description

This task is about providing contributors a more focused section editing experience through isolating content within the section and removing any unrelated copy.

User story

When I find a section of an article that I want to editI want to open an editor containing only the content of that sectionso that I can focus my attention on the content I actually want to edit.

General requirements

Platform: This feature will eventually need to exist for both desktop and mobile. Mobile should be deployed first.Languages: Editing team's target wikis Target users: Experienced and new editors who are using Visual Editor via the mobile webEventlogging: ??A/B testing: This feature should be A/B testable. We might want to test these sorts of things:

When people click on a section edit button, they're declaring their intention to focus on that section, and we should give them that experience. To do this, we can provide the user a new screen view that only displays that one particular section to edit to reduce stimulation

In terms of addressing the pain point of focus, these are routes we decided not to go for now, but might in the future:

create an orienting ui animation

refine the table of contents

tweak the toolbar

remove the need for refocusing completely, by creating a way to do sentence-level editing
